HBO previously released the official season seven key art which features the Night King. While this season was delayed from its normal spring premiere, it looks like for good reason. "Just finished reading season 7," Williams previously tweeted. "S—t gets REAL…I'd start preparing yourselves now…Scratch that, nothing will prepare you for this."

And yes, the start of season seven means the beginning of the end for the HBO fantasy drama, but that doesn't mean the end of adventures in Westeros. HBO is working on several spinoffs. Details are being kept under wraps but there is more than one project in the works to continue the tales of George R.R. Martin's characters.
